Sex differences in atrial potential morphology.

Background: Areas of conduction disorders play an important role in both initiation and perpetuation of AF and can be recognized by specific changes in unipolar potential morphology. For example, EGM fractionation may be caused by asynchronous activation of adjacent cardiomyocytes because of structural barriers such as fibrotic strands. However, it is unknown whether there are sex differences in unipolar potential morphology.

Quality of life improvement from thoracoscopic atrial fibrillation ablation in women versus men: a prospective cohort study.

Objectives: Thoracoscopic ablation has proven to be an effective and safe rhythm control strategy, especially for persistent atrial fibrillation. However, its impact on quality of life (QoL) and potential gender differences remains unclear.

Methods: This prospective, single-centre observational study included consecutive patients with symptomatic atrial fibrillation undergoing thoracoscopic ablation.

Closed-chest unilateral thoracoscopic ablation: box lesion with radiofrequency clamps only.

In this article, we describe the modified technique of a unilateral closed-chest thoracoscopic ablation and left atrial appendage closure including a box lesion that is made by radiofrequency clamps only for the treatment of atrial fibrillation. By abandoning the unidirectional pen devices and replacing these by radiofrequency clamps, we aim to further improve the procedural efficacy and shorten operation time while minimizing surgical exposure for the patient.

Long-term outcome after totally thoracoscopic ablation for atrial fibrillation.

Introduction: Totally thoracoscopic ablation for symptomatic atrial fibrillation (AF) refractory to drug or catheter based therapy is indicated as a Class 2A recommendation according to latest guidelines. Evidence for long-term rhythm control and stroke reduction is limited. The aim of this study was to report on long-term outcome after totally thoracoscopic ablation.

Totally thoracoscopic ablation for atrial fibrillation: a systematic safety analysis.

Aims: Thoracoscopic surgical ablation has evolved into a successful strategy for symptomatic atrial fibrillation (AF) refractory to other therapy. More widespread referral is limited by the lack of information on potential complications. Our aim was to systematically evaluate 30-day complications of totally thoracoscopic surgical ablation.

The Unstable Distal Radius Fracture-How Do We Define It? A Systematic Review.

Background Unstable distal radius fractures are a popular research subject. However, to appreciate the findings of studies that enrolled patients with unstable distal radius fractures, it should be clear how the authors defined an unstable distal radius fracture. Questions In what percentage of studies involving patients with unstable distal radius fractures did the authors define unstable distal radius fracture? What are the most common descriptions of an unstable distal radius fracture? And is there one preferred evidence-based definition for future authors? Methods A systematic search of literature was performed to identify any type of study with the term unstable distal radius fracture.

The Minimum Clinically Important Difference of the Patient-rated Wrist Evaluation Score for Patients With Distal Radius Fractures.

Background: The Patient-rated Wrist Evaluation (PRWE) is a commonly used instrument in upper extremity surgery and in research. However, to recognize a treatment effect expressed as a change in PRWE, it is important to be aware of the minimum clinically important difference (MCID) and the minimum detectable change (MDC). The MCID of an outcome tool like the PRWE is defined as the smallest change in a score that is likely to be appreciated by a patient as an important change, while the MDC is defined as the smallest amount of change that can be detected by an outcome measure.
